The Carmex Carbide Threading Insert – Unified – TiAlN Coated (30E6UN) is a versatile carbide insert system designed to tackle the majority of Unified thread profiles with reliability and precision. Perfect for machine shops and production environments, it combines durability, flexibility, and a streamlined tooling approach.
- Five length options: Available in 12 mm to 40 mm lengths, providing the right engagement depth for a wide range of thread forms and workpiece sizes.
- TiAlN coating: TiAlN coating boosts wear resistance and heat tolerance, helping the insert maintain sharpness and extend tool life in demanding materials.
- Double‑sided cutting edges: Most inserts offer two cutting edges, effectively doubling usable life before indexing (note: BSPT/NPT/NPTF/American Buttress/API RD are exceptions).
- Unified thread coverage: Engineered to cover all common thread profiles within a single system, reducing the need to stock multiple insert families.
- Internal & external threading capability: For many profiles, the same insert can machine both internal and external threads, streamlining setups and reducing tool changes (exceptions: ISO / UN / NPSM / UNJ / Acme).
- Carbide construction: Solid carbide core delivers rigidity, precision, and consistent performance across diverse threading tasks.
This threaded insert set supports pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI, depending on length), enabling efficient work on a broad spectrum of parts. Its cohesive design minimizes tooling complexity, helps you maintain steady production flow, and delivers dependable results on standard materials while offering solid wear resistance for tougher metals. Ideal for job shops and manufacturing cells aiming to optimize threading operations with a single, reliable carbide insert family.
